Boolean Algebra Simplify Expression

What is the first visual step often needed in Boolean expression simplification?

• Identifying the primary variables

• Rearranging terms using the rule of commutation

• Solving the expression directly

• Applying the distribution rule

What does the 'indent rule' state in Boolean algebra?

• x or x equal 1

• x or not x equal 1

• x and x equal x

• x and not x equal 0

According to the absorption rule, what does 'a or A and B' simplify to?

What is the result of applying the complement rule to 'A or not A'?

• Not A

• A

• 1

• 0

What does the identity rule state when applied to 'X and 1'?

• Not X

• 1

• 0

What is the effect of double negation in Boolean expressions?

• It converts ANDs to ORs

• It cancels out, leaving the expression unchanged

• It simplifies the expression to zero
